Description: The battleships of the world's navies in the 1820s were descended directly in line from the Revenge of 1577: they were wooden-built, sail-powered and mounted guns on the broadside, firing solid shot. In the next half century, steel, steam and shells had wrought a transformation, and, by 1906, Dreadnought had ushered in a revolution in naval architecture. The naval race between Britain and Germany that followed, led to the clash of the navies at Jutland in 1916. Though this was indecisive, the German navy never again challenged the Grand Fleet of Britain during the war, and eventually the crews refused to put to sea again. Disarmament on a massive scale followed, but the battleship was still regarded as the arbiter of sea-power in the years between the wars.
